Title:
DUAL CLUTCH TRANSMISSION MECHANISM AND START CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2012/070216
Kind Code:
A1
Abstract:
The heat load on a clutch at the time when a vehicle starts to move is reduced and the durability thereof is improved, and the clutch can be made smaller and lighter. A transmission control device (110), when a vehicle starts to move and with a prescribed number of even-numbered and odd-numbered transmission gears set via a shift mechanism (701), causes the torque capacities of two clutches to be transitioned to a certain proportion until the clutch rotation speed difference of a low-speed gear-side clutch reaches 0 or close to 0, sets the torque capacity of the clutch on the low-speed gear side is set to be the total torque capacity of both clutches and sets the torque capacity of the clutch on the high-speed gear side to 0.
